THROAT FOR BOTTLING-MACHINES.

Specification of Letters Patent.

Patented July 21, 1914.

Application filed January 15, 1910. Serial No. 538,184.

To all whom it may concern Be it known that I, HARRY L. VAUGHAN, residing in Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Throats for Bottling-Machines, of which the following 1s a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to a throat for use with bottling machines to clamp the crown cap to the mouth of the bottle and has for itsobject to simplify the construction thereof by forming the tapering composition metal throat piece of an integral ring instead of in segments, thereby reducing the cost of manufacture and enabling the throat piece to be readily renewed when worn wlthout the necessity for returning the throat to the manufacturer.

Another object of the invention is to provide spring actuated crown retaining dogs of novel construction which will be permanently held in place against accidental removal, but which will be freely accessible for repair.

Nith the above and other objects in view the invention consists in the throat for bottling machines herein described, its parts and combinations of parts as claimed and all equivalents thereof.

Referring to the accompanying drawing in which like characters of reference indicate similar parts in the different views: Figure 1 1s a sectional vlew of a throat em- *bodying one form of the invent-ion designed of line 33 of Fig. 4; Fig. 4 'is a bottom planview thereof with the sleeve sectioned to remove the retaining flange; Fig. 5 is a perspective view of the composition metal throat piece of the form of throat shown in Figs. 2, 3, 4 and 6; Fig. 6 is a sectional view taken on the plane of line 66 of Fig. 4;; Fig. 7 is a detail view of an implement designed for use in removing the throat piece from the casing; Fig. 8 is a transverse sec tional View of a throat, showing a further modification of the invention; Fig. 9 is a view thereof similar to Fig. 4, with a part sectioned to show the manner of seating the dog springs; and, Fig. 10 is a perspective view of one of the crown cap retaining dogs.

In these drawings 15 indicates a tubular casing with an inwardly extending annular flange 16 at its upper end forming an abutment for the thicker upper end of a throat piece 17 which tightly fits within the casing 15 and has a tapering bore for crowding to withstand the action of the crown cap such as 18in Fig. 3, to secure the cap to the mouth of a bottle when the bottle neck with the crown is forced into the tapering bore or throat-way of the throat piece. throat piece 17 consists of an integral ring of composition metal which is sufficiently hard to withstand the action of the crown cap teeth without becoming gouged thereby. The throat piece 17 is held within the casing 15 by means of. a flanged sleeve 19 which may he threaded on the casing 15, as shown in the forms of the invention illustrated in Figs. 1, 8 and 9, or which may have'a tight working fit on the outside of the casing, as shown in the form of the invention, illustrated in Figs. 2, 3, 1 and 6. The flange 16 of the. casing may be provided with a pair of openings 20 through which a pair of pins 21 of the repair implement shown in Fig. 7 may be inserted to engage the larger upper end of the throat piece 17 for driving said throat piece out of the cas ing after the sleeve 19 has been removed, said repair implement being struck on its upper cross piece 22 by means of a hammer for this purpose. The throat piece 17 is keyed in the casing 15, as shown in Fig. 3, by means of key pins.23 fitting in openings which pass through the flange 16 and are formed partly in the inner wall of the casing 15 and partly in the outer wall of the throat piece 17 and another opening 24 in the upper end of the casing forms a seat for a projection on the machine as usual.

With those forms of the invention shown in Figs. 2 to 9 inclusive, the casing 15 and the throat 17 are made somewhat longer than the corresponding parts in the form of the invention shown in Fig. 1, to provide sufiicient space beneath the lower end of the tapering throat way for crown cap retaining The dogs 25 which are relied upon to support the crown cap, as shown in Fig. 3, durln the filling of the bottle and until the bottle neck is forced within the throat way, To accommodate the dogs 25 the casing is provided with recesses 26 'at itsloweredge and registering openings 27v are formed in 5 the lower edges of thecasing and the throat piece through which the nose portions of the dogs project inwardly at a sufficient distance below the shoulder formed by the; beginning of the tapering throat way to preferably leaf springs 28 which may be let into slots 29 cut in the lower edge of the casing fromone recess 26 to another, as

shown in Figs. 3" and 4a, or which be contained within grooves 30 cut in the outer surface of-the casing near its lower "end, as

shownin Figs.8 and9. 'In'either case each spring "is designed to bear at'its opposite ends upon twobf thetdogs near the lower 30 ends thereof and to normally hold'said dogs in their inner position but permit'them to be forced outwardly'by the insertion of the crown cap as described. With the springs 28 'heldin the slots 29 in the end of the casing, as shown in Figs. 3' and 4, the flange of the sleeve 19 will serve to hold them in place without further: attachment, but with Y the'springs contained within the grooves 80, as shownin Figs. Sand 9, it is preferred to 40 hold them in place at their middle portion by means of screws 81. At'the opposite sides of the throat which are not occupied by the springs'QS there are formed theusual fill opening 32 andsnift opening33, which aolpenings pass through the sleeve 19 and'the t I roat piece 17 as well as'through the-casing;

Inoperation, the throat of the present in a vention performs the usual functions of throats for bottling machines and without the liability of the dogs becomin'gaccidh: tally withdrawn. A further advantage for the throat of' thisinvention isthat by'reason of'thecomposition metal throat piece being formed of an unbroken ring,,it is cheaper to manufacture and is quickly and v easily repaired when the tapering throat way has become worn, it being only necessary then to remove the sleeve 19 and the dogs 25 and drive the throat piece out of the casing by means of the repair tool shown 7 in Fig. 7 A new throat piece may then be inserted and is guided into its proper position to cause the several openings thereof ,toregister with corresponding openings iii the casing by fitting it to the key pins 23.

sleeve serving to prevent the removal of the v dogsfrom therecessesr This substitution of a newthroat piece for a worn one may. bev accomplished at the bottling establishment instead of havlng to send thethroat to the factory, and as the throat pieces may be sold separate for this purpose the renewal may be made'atalow cost and without loss of'time.

' WVhile various forms of the invention have been shown and described for the purpose of clearly disclosing the same, it is ,75 obvious that the invention is not limited to any specific 'form or arrangement of parts, except in so far as such limitations are specified in the claims.

What I claim as new and desire to secure 0 by Letters Patent is 1'. As a new article of manufactureQa throat piece adapted to. be removably se l cured within the head of a capping machine 7 comprising a tubular cylindrical casing pro- 5 v vided with an integral inwardly extending flange at the upper end thereof, an annular throat piece providedwith a tapered bore fitting within the interior 'ofsaid casing and abutting the inwardly extending flange thereof, said inwardly extending flange completely overlying the upper portion of the throat piece and beingprovided with an opening extending therethroughaffording access to the top of the throat piece, and means removably secured upon the lower end of the casing and underlying the lowerend of said throat piece for holding the same within the said casing.
